General Description
The MAX1832–MAX1835 are high-efficiency step-up
converters with complete reverse battery protection that
protects the device and the load when the battery is
reversed. They feature a built-in synchronous rectifier,
which allows for over 90% efficiency and reduces size
and cost by eliminating the need for an external
Schottky diode.
These step-up converters operate from a +1.5V to +5.5V
input voltage range and deliver up to 150mA of load cur-
rent. The MAX1833EUT/MAX1835EUT (SOT devices)
have a fixed 3.3V output voltage. The MAX1833ETT30
(TDFN device) has a fixed 3.0V output voltage. The
MAX1832/MAX1834 have adjustable outputs from +2V to
+5.5V. In shutdown, the MAX1832/MAX1833 connect the
battery input to the voltage output, allowing the input bat-
tery to be used as a backup or real-time clock supply
when the converter is off (see Selector Guide).
MAX183_EUT devices are available in a miniature 6-pin
SOT23 package. The MAX1833ETT30 is available in a
3mm
3mm thin DFN package. The MAX1832EVKIT is
available to speed designs.
